SpamHaus false positive on Ubuntu 24.04 + latest Cloudron
-
Hi,
Cloudron UI reports my IP as listed on SpamHaus, but check.spamhaus.org shows no issues for my hostname.
If I’m not mistaken, this was already addressed in an older release. I’m on Ubuntu 24.04 with the latest version of Cloudron.
The impact is real – some mail servers are rejecting outbound mail from my server with error 554 5.7.1. MX, DKIM, SPF, DMARC and PTR records are all green.
Is anyone else experiencing this on Ubuntu 24.04 + latest Cloudron? Thanks. -
Both today – sometimes it’s just one, sometimes both.
